7 Claims.

This invention relates to a bolt-holding attachment for pliers whereby abolt may be held in position, also held against rotation while a nut isbeing threaded onto the bolt and seated.

An object of my invention is to provide a novel attachment which ismounted on one of the jaws of a plier and which is so positioned andarranged that the head of a bolt may be engaged and held in position inorder that a nut may be threaded onto the bolt with one hand while theother hand is used to operate the pliers.

Still another object is to provide a novel boltholding attachment forpliers which can be quickly and easily attached to a jaw of the pliers,or removed therefrom as desired, and which is simple in construction andinexpensive to manufacture.

A feature of my invention resides in the manner in which thebolt-holding finger is mounted so that the jaws of the pliers aresufficiently spaced from the bolt to permit the nut to be threaded ontothe bolt and seated without removing or shifting the pliers.

Other objects, advantages, and features of invention may appear from theaccompanying drawing, the subjoined detailed description, and theappended claims.

In the drawing Figure 1 is a side elevation of my bolt-holdingattachment in position on a pair of pliers.

Figure 2 is a top plan view of the same.

Figure 3 is a longitudinal sectional view of the bolt-holdingattachment.

Referring more particularly to the drawing, the numera1 I indicates apair of pliers which includes the usual jaws 2 and 3 formed on the endsof the handles 4 and 5. My bolt-holding attachment 6 comprises a hollowcap or thimble I which is so formed that it fits over the end of one ofthe jaws 2 or 3 of the pliers.

A pair of straps 8 and 9 are formed on the top side of the thimble 1 andmay be either integrally formed with the thimble or fixedly attachedthereto. These two straps are spaced apart substantially as shown. Afinger I is guided in the straps 8 and 9 and projects forwardly of thethimble I a substantial distance, this finger being provided at itsouter end with a laterally disposed tip u. The outer end of the tip isbeveled to form a screw driver point for engagement with the kerf orslot formed in the head of a threaded bolt. If desired, the tip H may beformed with a socket for en'- gagement with the angular head of a bolt,where such head is not formed with a tool engaging slot. A set screw l2extends through a slot l3, formed in the finger l0 and is threadedthrough an opening provided therefor in the top face of the jaw 2 or 3,thus holding the attachment in position and also holding the finger I 0against longitudinal shifting.

Usually a bolt extends through two or more plates and is spaced somedistance from the edge of these plates. The pliers l are opened and thefinger I0 is extended to a suitable distance so that the point II canengage the kerf in the head of the bolt while the jaws of the pliersclamp the plates through which the bolt extends. With one hand, theworkman holds the plier in clamped engagement with the plates, with thetip II engaging a slot in the head of the threaded bolt that extendsthrough the plates, and this tip will hold the bolt against turning,while a nut is being threaded on the shank of the bolt.

Having described my invention, I claim:

1. In combination with a pair of pliers including a jaw, a, bolt-holdingattachment comprising a thimble fitted over the end of the jaw, aboltengaging finger mounted on the thimble extending outwardlytherefrom, releasable means on the thimble engaging the jaw whereby thethimble is held on the jaw, and means adjustably mounting said finger onthe thimble.

2. In combination with a pair of pliers including a jaw, a bolt-holdingattachment comprising a thimble adapted to fit over the end of said jaw,a guide strap on the thimble, a finger extending through said strap andheld thereby, a bolt-engaging tip on the finger, and a setscrewextending through the finger and through the thimble, said setscrewbearing against the jaw whereby the attachment is held in position onthe jaw.

3. In combination with a pair of pliers including a jaw, a bolt-holdingattachment comprising a thimble adapted to fit over the end of said jaw,a guide strap on the thimble, a finger extending through said strap andheld thereby, a bolt-engaging tip on the finger, and a setscrewextending through the finger and through the thimble, said setscrewbearin against the jaw whereby the attachment is held in position on thejaw, said finger having a slot therein through which the setscrewextends.

4. .A bolt holding attachment for a pair of pliers comprising a thimblefitted over the end of one of the jaws of the pliers, means forremovably securing the thimble on said jaw, a member adjustably securedon the outer side of the thimble, the outer end of said member extendingbeyond the forward end of the thimble and the outer end of the jaw onwhich the thimble is mounted, and bolt head engaging means formed on theprojecting end of said member.

5. A bolt holding attachment for a pair of pliers comprising a thimblefitted over the end of one of the jaws of the pliers, means forremovably securing the thimble on said jaw, a member adjustably securedon the outer side of the thimble, the outer end of said member extendingbeyond the forward end of the thimble and the outer end of the jaw onwhich the thimble is mounted, and a laterally extending bolt headengaging tip formed on the outer end of said member.

6. A bolt holding attachment for pliers comprising a thimble removablyfitted over the end of one of the jaws of the pliers, a member slidablymounted on the outer side of the thimble, guide means for the slidablemember arranged on the outer side of the thimble, means for securing thethimble on said jaw and for holding the member in its slidably adjustedposition on the thimble,

the outer end of said member projecting beyond the outer end of thethimble and the outer end of said jaw, and bolt head engaging meanscarried by the outer end of said member.

7. A bolt holding attachment for pliers comprising a thimble removablyfitted over the end of one of the jaws of the pliers, a member slidablymounted on the outer side of the thimble, guide means for the slidablemember arranged on the outer side of the thimble, means for securing thethimble on said jaw and for holding the member in its slidably adjustedposition on the thimble, the outer end of said member projecting beyondthe outer end of the thimble and the outer end of said jaw, and alaterally extending bolt head engaging tip formed on the outer end ofsaid member.
